3 Description

The TAS5753MD device is an efficient, digital-input

audio amplifier for driving stereo speakers configured

as a bridge tied load (BTL). In parallel bridge tied

load (PBTL) in can produce higher power by driving

the parallel outputs into a single lower impedance

load. One serial data input allows processing of up to

two discrete audio channels and seamless integration

to

most

digital

audio

processors

and

MPEG

decoders. The device accepts a wide range of input

data and data rates. A fully programmable data path

routes these channels to the internal speaker drivers.

The TAS5753MD device is a slave-only device

receiving all clocks from external sources. The

TAS5753MD device operates with a PWM carrier

between a 384-kHz switching rate and a 288-kHz

switching rate, depending on the input sample rate.

Oversampling combined with a fourth-order noise

shaper provides a flat noise floor and excellent

dynamic range from 20 Hz to 20 kHz.
